Are express.js Request events documented anywhere?

Question

It seems to be common community knowledge that Express Request objects have events like req.on('data', …) and req.on('end', …), but the official documentation – https://expressjs.com/en/api.html – makes no mention of these events.

Are Express' Request events documented anywhere? And what – if any – guarantees are made about them?

Here is the docs for nodejs request
